Hello -SAMSUNG Refrigerator RF266AEPN - Compressor not running. Only 2 years old.The LED on the inverter board flashes once at a time which seems to indicate starting failure.I could not find exact match for a service manual on this forum. Manual for RF266ABxx does not entirely apply as RF266AEPN has a separate inverter board while RF266ABxx does not. So I used Fast Track RFG29PHD which looks similar from electronic point of view.So I tried the following:1. Activate Forced Compressor Operation, wait 2 minutes (in case of high head pressure): Compressor did not start2. If compressor doesn’t start, check CN75 for 2.5vdc (if not there replace Main PCB) : I found no voltage in pin 4 of CN75 - but again this is assuming the same configuration on my board.3. If voltage is OK, remove power, disconnect CN03 (Inverter PCB) and check resistance to the windings. Aproxametly10 ohms: The resistance was good.

Assuming the same configuration, it seems I need to change the main board. However I want to make sure I am not going to have to change all the boards and the compressor (which in that case Samsung warranty should cover). Would anyone have the service manual for this refrigerator or could confirm the same configuration and conclusion applies?

Had simular promblem and it was the main power board.Only 2 years old would not think compressor failure.

I got a new board. Same readings. Same problem. The compressor does not start.The test below seems wrong for my model. My model code number is RF266AZPN/XAA. "If compressor doesn’t start, check CN75 for 2.5vdc (if not there replace Main PCB) : I found no voltage in pin 4 of CN75 - but again this is assuming the same configuration on my board"
